Abstract
The title coumarin derivative, C20H14N2O3, displays intramolecular N—H⋯O and weak C—H⋯O hydrogen bonds, which probably contribute to the approximate planarity of the molecule [dihedral angle between the coumarin and quinoline ring systems = 6.08 (6)°]. The supramolecular structures feature C—H⋯O hydrogen bonds and π–π interactions, as confirmed by Hirshfeld surface analyses.
